noon waxmq AND Application illed May 17,

This invention'relates to floor waxing and polishing machines and hasfor one of its objects to provide a machine of th1s character which willbe simple in construction,

comparatively inexpensive to manufacture and more efficient in use thanthose which have been heretofore pro osed.

A further object of the nvention is to provide a machine of the classdescribed 111 which the driving motor is housed in an isolated chamberto the end that it may be protected from the dust and wax particleswhich are necessarily thrown ofif by the rotatingwith a layer of waxwhich has necessitated a cleaning ofthe machine every time it 1s used,

With the above and other objects in view which will appear as thedescription proceeds, the invention consists inthe novel details ofconstruction andcombinations of parts more fully hereinafter describedand particularly pointed out in the appended claims. 1

Referring to the accompanying drawings forming-a part of thisspecification in which like reference characters designate'like parts inall the views:

by the line 4-4 of Fig. 3, looking in the direction of the arrows; Fig.5 is a top plan view of the machine as shown' in Fig. 1; I

Figs. .6and 7 are respectively side eleva- 65 tional and end?elevational views showing in detail, the motor mounting; and,

Fig. 8 is a longitudinal vertical sectional view through the frame orhousing with the motor and-brush omitted-and taken a proximately on theplane indicated by t e line 8--8ofFig.3. v Referring to the saiddrawings the numeral 10 indicates generally the housing of the machinewhich comprises a central main sec- "tion 11 and the laterally offsetportions 12 r and 13. The sidewalls of the said sections 12 and 13extend forwardly and have mounted therein, a shaft 14 which ispreferably retained in place by the bolts or screws 15, as will bereadily understood. The ends ofthe said shaft are reduced as at 16 toreceive the antifriction bearings 17 upon the outer races of which ismounted the-drum of the brush 18 which is provided with suitable tuftsof bristles 19, as will be clear from As will be noticed from Figs. 3and the brush 18 at one end, extends close to the wall of the offsetportion 12 while at vits other end, it is provided with a pulley 20around which passes the belt 21 for driving the brush.

The housin 10 is provided with a transversely e'xten ing partition wall22, see Figs.

2, 3, 4 and 8, which divides the said housing into a brush chamber 23anda motor chamber 24. The said partition wall 22 is imperforate except forthe opening 25 pro-"- vided within the. offset portion 13 and throughwhich the driving belt 21 is adapted to pass, as will be readilyunderstood from the drawings.

A motor 26 is mounted'in the motor chamber 24 in any suitable manner butpreferably I by means of the pendulous suspension shown :in detail inFigs. 3, 6 and 7. This suspension as will be clear from the saidfigures, comprises the reversely positioned U-shaped strap members 27and 28 carried respectively A by the main portion 11 of the housing andp -the motor 26, with their ears 29 and 30 piv otally connected by meansof the rod or shaft I 31 extendin therethrough.- An L-shaped imperforateexcept for the opening so that the motor chamber 24 is substantiallycompletely isolated from the brush chamber 23. It therefore follows thatthe said chamber 24 and the motor 26 are completel protected from dustandwax particles t rown off by the brush 18, except for the said opening25. In order to prevent such foreign matter from finding its way throughthis opening, there is provided a longitudinally extending wall 36running forwardly from the transverse partition 22 in close proximity tothe lower end of the brush 18, as viewed in Fig. 3. This said wall '36is cut away as at 37 to closely follow the contour. of the drum of thebrush 18, (see Figs. 2,

3 and 8,) and it therefore follows that dust and wax particles will beprevented by the said partition wall from finding their vway' throughthe belt opening 25 in the transverse wall 22 so that the motor will becompletely protected from such foreign matter.

In rior machines of this character it has been ound'that the heatnecessarily generated by the operation of the electric driving motor hasbeen so great that the wax par ticles thrown off by the revolving brush.have been melted upon the various parts of the machine and fused into. asolid coating covering such parts. It has, therefore been necessarywiththe prior machines to scrape off or otherwise remove this wax coatingeach time the machine is used, which operation has been exceedinglydiflicult and disagreeable.

order to overcome this objection in the present instance, meansare-provided not only for excluding wax particles from the motor chamberbutalso for efficiently ventilating and cooling said motor. As will-beclear from Figs. 3, 4, and 6, the driving shaft 34 v of the motor 26 isprovided on the end opposite-to that carrying the driving pulley '35,with a fan 40 and the side walls of the housing 10 are provided withsuitable ventilating openings 41 through which cool air may be drawn anddischarged by the action of the said fan 40 thereby effectivelydissipating the heat necessarily generated'during the operation of themotor. The dis.-

.sipation of this heat naturally will prevent the melting of any waxparticles which may be deposited anywhere upon the housing 10 and ittherefore results that the cleaning operations above mentioned need notbe performed as frequently with "the present machines as is the casewith the prior machines. I

A portion of the air blast from the fan 40 will also be dischargedthrough the opening 25, thereby further preventing the entry of foreignmatter into the motor chamber through said 0 ening.

In order to a 0rd access to ber 24, a removable bottom late 42 isprovided which is normally held in position by suitable screws or otherfastening means 43 engaging the ears 44.

For manipulating the machine, handle 45 is the motor champrovided, whichmay be similar to the well known vacuum sweeper handle and which carriesthe conducting wires 46 for supplying current to the motor 26; The saidhandle may be provided with a control switch 47 and with suitable clipsor brackets 48 upon which the electric cable may be wound when notinuse.

It will thus be seen that the present invention provides a floor waxingand polishing machine wherein the motor is mounted in an isolatedchamber where it is effectively protected from dust and wax particlesand that means are provided for ventilating and cooling this chamber tothe end that the heat generated by the operation of the motor will notmelt the wax and cause the formation of a coating of wax upon thehousing. It will also be clear that owing to the peculiarconstructionwhereby one end of the brush 18 is brought into closeproximity with" the side wall of the offset 12 that the machine may berangements of parts without departing from I the spirit of the inventionand therefore it is not wished to be limited to the above except as maybe required by the claims.

What is claimed is 1. A machine of the class described, comprising ahousing having a, transverse partition wall dividing it into a brushchamber and a motor chamber, said wall having an 'opening therein; abrush mounted in said brush chamber; a motor mounted in said motorchamber; driving connections between said motor brush passing throughsaid opening; and a second partition wall disposed at an angle to saidfirstwall and extending into said brush chamber, adiacent one end ofsaid brush, said second wal being cut away to conform substantiallyto'the periphery of thebrush drum, for preventing foreign matter frompassing to said motor chamber through said opening.

2. A machine of the class described, colnprising a housing having atransverse part-ition wall dividing it into a brush chamber and a-motor'chamber, said wall having an a brush mounted in said opening therein;brush chamber; a motor mounted in said motor chamber; drivingconnections between said motor and brush, passing through said opening;a second partition wall extending forwardly from said transverse Wallinto said brush chamber, coacting with said brush to prevent foreignmatter from passing through said openinginto said motor chamber; and afan in said motor chamber driven by said motor, adapted to force airthrou in said opening into said brush chamber, an thereby also preventforeign matter from passing through said opening into said motor cham-3. A machine iii the class described, com
